lMPR-OVEM ENT IN CULTIVATORS.

Specification forming part of' Leiters Patent No` 98,970. dated January 18, lATU.

Be it known that I, B. S'. HYERs, oiPckin, in the county of Tazewell and State of Illinois, haveinvented certain new and useful Improvements iirCultivators 5 and I do hereby declare that the following` is a full and exact description thereof, reference being had to the accompanying drawings, forming part of this letters ot reference marked thereon.

My invention relates t mentsknown by agriculturists as the wheelcultivator,77 and its objects are to construct and arrange the plows of the cultivator to the frame and connecting the-draft in such a manner as to cause the whole to make it easy both for the team and operator to work the same, as every part readily adjusts itself to the motion of the horses, and the attachment of the beams of the plows to the axles or frame can be sadjusted as toregulate the gage of depth ofthe plows,fand also the line of draft in the ls oi' soil, at the same time they can be made to conl'orm to all the sinuosities ol' the rows.

The nat-ure ot' this inv viding a straight wrought-ir0n axle, in comination with the wheels and frame for each wheel, cach axle being independent of -the other, and eachsnpporting the respective sides ofthe frame.

It also cousistsinthe use of cast-iron or other suitable supports or clamps made in longitudinal sections and of peculiar and novel form, in combination with curved orother properlyformed wrought or cast iron braces or supports, clamped together with the other mentioned east-iron supports around each axle, l'or the purpose otits ready detachment and to support the frame.A

It further consists in the employment of two adjustable laterally-inclined braces, in combination withv the before-mentioned clamps and tongue, to prevent any lateral movement of the frame whenthe plows are set to throw the soil toward the'plants, and to elevate or lower thcinner ends ofthe axles, as may be desired, for the purpose ol' taking up the slack in the clevises and joints in the work` machine.

Another feature of 1n make a direct attachmentof the beams of the forward of the wheels,

o that class of impleention consists in proy invention is that I l port of the frame throu bination of a slidin Abe of wood or iron of com tance, and toy these s yother means, tw

through the medium of clevises androds arranged in such a manner as to receive the sup-` gh the medium of the tongue; also, for thefurther purpose of regulating the draft or pressure on the horses necks by means of an adjustment provided for this purpose.

It also consists in fitting the elevis on the inner end of the axle and providing the same with two or more notches, in combination with a sliding socket, sothat the distance .of the plows from eachother may be changed to aecommodate them to the width of the rows, as will be more fully explained; also, a sliding piece made to move on the axle and within the clevis, which is provided with three or more holes for the purpose of attaching the plows to the same. .so that they may be moved or changed on thisfas well as on the axles, thereby securing a wide range for the plows sufficient to add another plow;l also, the com g piece on the axle with the clevis, each provided wit-l1 corresponding holes, so that a pin maybe inserted for the purpose ot' making the plows rigid to and to preventthe plows tak course when the soil is light and the 'rows straight, and for the purpose of avoiding the necessity of holding the same by hand.

'l To enable others skilled in the art to make and use my invention, l will proceed to describe its construction and operation.

Figurel is a top plan view of my improved cultivator. Fig. II .is a longitudinal sectional elevation of the same, taken from thc-line XX.

Letters of like name and kind indicate like parts in cachot the figures. p

A and A represent two wheels, which may mon construction that run on inde- B and B', upon ronght iron straps ard to a proper disaid straps are bolted curved braces D D D I), upon the top and at the outer end of which are secured, by bolts or o cross-bars, E E, and to these -is secured the pole or tongue F, by which the machine is guided while being operated. These parts now described constitute the frame of my cultivator, which is carried and supported on the Wheels A A and axles B B.

.G and G represent the cultivator or plow and of suitable dimensions, pendent and separate axle which are clamped cast or w C C', extendingv upw the frame,` ing a sinuous` beams, of suitable dimensions to carry and supportthe plows aa a a, secured to the standards e e, thelatter of which are secured by means of pivot-bolts to the beams G G, so as to allow then to lbe adjusted to any desired inclination, 'and are held rigidly in their position vby means of braces oro o o, on which are screwnuts and following nuts to holdthe said standards in position.

SIS are laterally-inclined braces, thelower ends of which are connected to the upper portion or ends of the clamps C O,'and the other ends arev secured underneath the tonguein such a manner as to allow them to be elevated and lowered,so as to set the tread ofthe wheels. out or in, as may be desired, and to prevent` the wheels from spreading apart when in operation.

On the forward end of the beams G G'lare clevises H H, the front ends of which are made broad, so as to admit of several holes being made therein for the purpose of changing the line of draft, or to allow other pins to be inserted to make the beam rigid to the axle when the soil is light and the rows straight, under which circumstances this can be done, at the same time avoidingthe necessityzo'f the operator guidingthe plows by the handles I I, y which aresecured to the rear end of the beams..

-J J are'sliding or' movable lugs, the rear ends of Whichare made to exactly correspond and fit inthe clevises H H. rI hese lugs are made to move laterally with'the line of draft, so as' to throw the plows farther. apart when desired. 'The rear ends ofthese lugs are elevated, so as to'cause the plows to run shal-v lower, and if found to run too deep they can be reversed or turned upside down, which will materially cl1ange the running ofi the plows. The position of theselugs will be governed by the nature of the soil.

l K is aso-rt ofdoubletree,secured or attached to the under side of the tongue by means of l staplesr or other device.

L L- are pendent bars or rods, attached to each end of the said doubletree by means of staples and hooks :or other sui-table means.

M M are cockeyes fitted on each axle,which stride the movable lugs before described. At the front end of each of the cockeyes are rods or links W W, that connect `with the pendent bars or rods LL; also,to these pendent bars are `connected other rods, N N, that extend .,.foiiiward andonnect-xvithihebow-O, the..1at ter of which is connected to the under side of the tongue. The front ends of the rods N N are provided with hooks that pass through place to place.

when it is desiredto move the cultivatorfrom j The operation is simple, .eas'y, and effective, I' consisting in attaching the jteam` to therodsN N, the plows being adjusted according to the nature of thesoil and the work to be done.

When it is desired to move thecultivator from place to place, the rear ends of theplow` beams can be raised and secured in an elevated position by means of hooks provided for that purpose. y

Vhen the line of draft of the plows `is re quired to be-changed. the clevis can be moved to one of the outer holes in the lug,'thus changing the line of draft, as"desiied,\and when the plows are required to be set farther apart the plows and lug can be elevated, so as" to allow y the projection or lug in the'cockeye to pass by the notch in the sliding lug, and when they are loweredv they must retain their position. y

Having thus described my invention, what I claim'as new, and desire to secureV by Letters Patent ofthe United States, is-

1. The two straight axles B and'BQindependent of each other, inv combination with the straps C C,"substantially las herein shown and described,and for the purposes set forth.

` '2.. The two .adjustable 'laterally inclined,"

braces S S, in combination with the straps or clamps C C andtongue F, substantially as shown and described, and for the purposes set forth. l v' 3. The sliding lug within the eekeye M.

providedlwith one or'l more notcheaso as to allow it to pass bythe clevis H, substantially Y as herein shown and described.

4. The cockeye M, in Combination with the' sliding lug J and rod or link W, 'substantially as and lfor the purposes set forth.

5. The combination and arrangement of the clevis lH and sliding lug J, provided w-ith holes for pins or bolts, .so-as to make theplows rigid to the line of draft, substantially 'as herein shown and described. v
